Abstract
Methyl esters of vegetable oils have been successfully evaluated as diesel substitute. In the present study, other alkyl esters, namely ethyl and isopropyl esters of crude palm oil and crude palm stearin were synthesized via chemical transesterification reactions and subsequently evaluated for their fuel properties. Generally, these alkyl esters exhibit higher viscosity (4.4Ã10â6m2/s-5.2Ã10â6Â m2/s) compared to that of petroleum diesel (4.0Ã10â6Â m2/s). However, compared to petroleum diesel, these alkyl esters exhibit acceptable gross heat of combustion (39-41Â MJ/kg). Originated from renewable origin, the low sulfur content in alkyl esters emits much lower SO2. These alkyl esters are much safer than petroleum diesel in terms of safety for storage and transportation as they possess high flash points. They may find applications in the fuel industry besides utilization as oleochemicals.
